Systems

Tropical Cyclone Angele

Angele form on December 13, while stationed in the middle of the Mozambique Channel. It traveled north and gradually organized into a tropical storm while performing a tight counter-clockwise loop. On December 18 Angele intensified into a tropical cyclone before making landfall on Mozambique. Angele weakened to a tropical storm while over land, but re-intensified back to a tropical cyclone as it re-emerged into the Mozambique channel. The cyclone moved south and quite abruptly, on December 23, moved to the northeast. On December 24 Angele reached a peak intensity as a category three cyclone. The system weakened slightly before making landfall on Madagascar two days later. The weak storm moved over the open Indian Ocean and translated into an extra-tropical storm.
